Typically, members are usually shareholders and their liability is limited to the nominal (nominal capital is defined as the capital with which the company was incorporated) value of their shares plus any unpaid amount on their shares.

As an example, say you buy BHP shares at $10 for 100 shares, then your liability is limited so that if BHP were to be sued, it is limited to the $10 paid.This is sometimes conducted differently when you don’t fully pay for shares when the company floats. If $5 was paid and $5 was then owed on the shares, then the remaining amount must be contributed should it be called upon.
